“…The negative affect scores included eight items, which were measured on a 1-5 scale. To measure and match the task load of each cognitive task, we used the NASA Task Load Index (Japanese version; Haga & Mizukami, 1996; Fig. 1 ).…”

The successful regulation of emotion relies heavily on executive function. Until very recently, however, the specific effects of executive function activity on other processes havereceived relatively little empirical attention.The link between executive function and emotional responses suggests that the activation of executive function may play an important role in the attenuation of emotional responses. We conducted twoexperiments to test the hypothesis that decrements in emotional responses following cognitive task performance might be caused, at least in part, by the activation of executive function.First, we sought to test whetherthe activation of executive function reducedemotional responsesimplicitly, without any volitional effort.Next, we sought to examine the link between prior activation of executivefunction and the attenuation of subsequent emotional responses, by comparing the effects of an executive-function-demanding task with the effects of a task that is equally effortful but does not engage executive function.We discuss our results in the context of the role of executive function in the attenuation of emotion.

A methodology to increase driver trust in rear-obstacle warning systems with imperfect sensing results — Proposal for a warning system using sensor reliability information

a b s t r a c tDriver's workload tends to be increased during driving under complicated traffic environments like lanechanging operation. In such cases, rear collision warning is effective for reduction of cognitive workload. On the other hand, it is pointed out that false alarm or missing alarm caused by sensor errors leads to decrease of driver trust in the warning system and it can result in low efficiency of the system. Suppose that sensor reliability information is provided in real-time. In this paper, we propose a novel warning method to increase driver trust in the system even with low sensor reliability by utilizing sensor reliability information. We investigate the effectiveness of the warning methods in high and low workload situations by driving simulator experiments.

“…NASA-TLX is the technique for requesting the load index of the task based on a multi-dimensional average of subjective information. In our research, we use the Japanese Version of NASA-TLX proposed by S.Haga et al [11]. The evaluation of this experiment include measures of the physiological load by examining their brain waves as well as the psychological load by using NASA-TLX.…”

Abstract. The purpose of this research is to support office workers to participate in multiple teleconferences simultaneously. In order to achieve this goal, we have investigated how people understand multiple voices that differ in conditions of overlapping rates. We have evaluated comprehension of the context and the keywords in multiple voices, which is necessary for the users to participate in multiple teleconferences. In addition, we have described the psychological load of the users by using NASA-TLX as the workload index and the physiological load by examining the brain waves of the users. From the experiment, we can show three factors. First, we found more than half of the examinees understand the context when the voices are overlapped completely. Second, little of no difference is observed in the level of comprehension of keywords, between when the voices are half overlapped and overlapped completely. Third, it can also be suggested that examinees are more uncertain of their answers when the voices are overlapped completely compared to when they are only half overlapped. As for the load of the users, our results suggested that imperfect overlap amplifies the psychological load. Based on these results, we will discuss the necessity of selecting appropriate overlap rates and design the environment of multiple teleconferences.
